What's needed to deliver complex cloud solutions
Bill StrainCTO iomart
A Quick History
Vmware launch 2000SWsoft launch 2001Xen Launch 2003Amazon launch 2006
What can we do with it
Create servers on demandEasily flexing the requirements either horizontally or verticallyPay only for resources used
What can we do with it
Web serversTestingDevelopmentStandalone server
What are the limitations
Contention Limited SLA’sMulti-tenantedInter machine communication can be limited
What is pushing us to the cloud
• Rental model • Scalable• Flexible• Reduced lead times • More bang for the buck• Possibly a solution to lower Co2 • More resilient• Fashionable technology
What is holding us back
Noisy marketConcerns over securityMistrust of cloud SLA’s Dinosaur tendency Mistrust of real-world performanceLegacy systems are difficult to portPerception “Cloud” means Amazon Only for Techies or non-critical systems
Where are we going
Most new product or systems development will have “Cloud” concepts built in from the start.IT departments/Service providers under pressure to reduce costsCustomers being bombarded with “Cloud” from every direction.Major vendors now pushing the “Cloud” model (Cisco, Oracle, Microsoft)Terminology now settling down (Cloud, Private, Hybrid)
1st generation Cloud has moved to the mainstream
What do our customers need
On demand VM’sFlexible CPU, RAM storageFlexible billing
What do our customers need
On demand VM’s within limitsStrictly managed contentionSecurity – strict separation of network and data
What do our customers need
Legacy systemsHigh performance applications
What do our customers need
Secure communication between all serversShared data between servers
Key factors we need to deliver
• High availability• High speed communication• Security
• Flexibility• Control
Highly resilientHigh speedMultiple redundant network providers
Network Layer
Choice of virtualisation technologiesHigh availability on Xen and VMwareHigh specification Dell & HP
Virtualisation layer
Storage Layer
Highly resilient – no data can be lostStorage had to be shared between platforms Storage had to be shared or available across DatacentreScalable I/O performanceSimple provisioningSimple migrationReporting on LUN QOSNo vendor lock in
Storage Layer
Allow customers to provision VM’s across platformsProvide reporting on VM’s and serversProvide monitoring on VM’s and servers
